No he is not. He has an MBA from Golden Gate University and then a PhD in Public Administration from the University of Alabama. These are not a front line schools or programmes. Given these qualifications he is not an economist either. The qualification is in Business and/or Administration. In our terms he is not a Professor, but rather was a sessional lecturer at Iowa State on their MPA but most of his teaching experience is at Morningside College (me neither). Most damning for his claims to be an academic (or suitability for the position of Under Secretary of Agriculture) is that he is almost completely unpublished in peer reviewed journals.
He did say this though 'At the end of the day, scientists are nothing more than a bunch of dumb, regular people with limited vision who think dinosaurs actually existed and the earth is somehow getting warmer'.
In short, he is a fat buffoon who supports Trump. Please don't accuse him of being an economist though. That is moderately unfair to us economists. He was a radio talk show host though.
